Explaining h -> mu(+/-)tau(-/+), B -> K*mu(+)mu(-), and B -> K mu(+)mu(-)/B -> Ke(+)e(-) in a Two-Higgs-Doublet Model with Gauged L-mu-L-tau

摘要

The LHC has observed, so far, 3 deviations from the Standard Model (SM) predictions in flavor observables: LHCb reported anomalies in B -> K*mu(+)mu(-) and R(K) = B -> K*mu(+)mu(-)/B -> Ke(+)e(-), while CMS found an excess in h -> mu tau. We show, for the first time, how these deviations from the SM can be explained within a single well- motivated model: a two-Higgs-doublet model with gauged L-mu-L-tau symmetry. We find that, despite the constraints from tau ->mu mu mu and B-s-(B) over bar (s) mixing, one can explain h -> mu tau, B -> K*mu(+)mu(-) and R(K) simultaneously, obtaining interesting correlations among the observables.
